 Note: being the uneducated plebeian that I am, I have not actually done the physics/engineering calculations on this and could be very very wrong. I'm still trying to learn how to translate magnetic field strength (gauss/tesla) into force (newtons).
+===== Update ======
+I have evidence showing that a magnetic field around the rail gun absolutely improves efficiency. This can be from permanent magnets or from coils. This changes my design a tad, but increases the likelihood of functioning.
+===== Next Steps ====
+I think the ultimate design will be rails and electromagnets--Neodymium magnets *might* be strong enough on their own, but I think a good coils design will prove much more powerful (and much cooler to look at and build).
+==== Step 1: Bench Top POC ====
+I need to prove for myself that the basic design works. I've been (for years now) getting caught up on making rails that will last a long time and be extremely functional--this has been stalling progress on this project. The benchtop model will be just good enough to work. It will use cheap steel for the rails, permanent magnets, and a benchtop PSU.
+=== Tasks  ===
+  - [[http://www.instructables.com/id/Convert-A-Computer-Power-supply-to-a-Bench-Top-Lab|Build a benchtop PSU]] (from a computer PSU)
+    * Need old PSU, resistors, heatshrink tubing, terminals, LEDs, cool switch -- most should already be kicking around
